80,000-year-old “arrowheads” rewrite human history

Archaeologists have identified tiny 80,000-year-old projectile points in Uzbekistan that may have been used like arrowheads. Their size, design, and impact damage closely resemble weapons found much later at a Homo sapiens site in France. The discovery suggests sophisticated projectile technology may have appeared in Central Asia long before modern humans became firmly established in Europe, potentially rewriting a major chapter of human migration.
